For what it's worth, I needed to add libzstd-dev to the build dependencies of littler while backporting it to Debian bookworm (not for bullseye). Sorry, I have no deeper insight but that is what I experienced.
Could it be related to this R 4.5.0 NEWS entry: - There is some support for zstd compression of tarballs in tar() and untar(). (This depends on OS support of libzstd or by tar.)
